3D cell imaging by tomography

Estier is a high-level optical coherence tomography (OCT) instrument that allows non-invasive analysis of 3D structures, including microvessels/tubular structures, tissues, spheroids and organoids.

As OCT provides an advantageous platform to conveniently visualise the in vitro and ex vivo dynamics of 3D structures, it can be used as an alternative visualisation/monitoring method to obtain quantitative information on morphological changes occurring in 3D cell culture samples.

Estier OCT technology enables label-free, non-invasive tomographic imaging and monitoring of microvessels, neovascularisation formation to quantify and assess morphological changes in a short time. Ideal for tumour invasion testing and molecule efficacy assessment.

The ability to measure the actual volume (X, Y and Z directions) of 3D structures (spheroids/organoids) allows true comparison of drug efficacy in preclinical models.

Detects necrotic regions and quantifies volume, internal cavities, tubular structures, etc., with impressive focus.

  1. 3D morphological analysis of cultures / internal structures with OCT. OCT is a non-invasive technology that can be used to acquire the tomogram of a living cell or organism using weak near infrared light.
  2. Time-lapse observation by non-invasive and label-free analysis Real-time observation of spheroid formation at collapse after addition of an anti-cancer drug Detailed observation of the 3D structure of spheroids that conventional microscopes cannot recognise
  3. Compatible with all standard micro well plates (SBS format) and culture dishes Specific well plates optimised for 3D culture, including Corning® Elplasia®, can be used for imaging SCREEN offers customised solutions to our researchers. These include the implementation of custom plate formats, such as microfluidic chips, organ-on-chips.

Non-invasive deep tissue imaging

Allows non-invasive detection of internal cavities and tissue lacunae (up to 1 mm thick). A 3D image of 300 μm2 can be acquired in 1 minute. High-resolution (3 μm) and low-resolution (10 μm) imaging options (focus range 1 μm-10 μm) with precise focus options in vitro drug screening


Easy to use

User-friendly workflow. No special training or technical expertise is required to operate the system and perform image analysis. Allows differentiation of samples by detecting image contrast from variances in the physical density of the sample (refractive index (RI)) Bright field imaging.


User-friendly analysis software

Dedicated software facilitates rapid 3D data acquisition and image reconstruction.

Simple, straightforward user interface requiring no extensive training or operational expertise


Compatibility of cell culture media

Any standard cell culture material such as microwell plates, etc., can be used. The system can be integrated into any existing workflow.

No special laboratory equipment or reagents are required.
